WRITING INSTRUMENT.

Specification of Letters Patent.

Patented May 1, 191?.

Application filed April 15, 1911, Serial No. 621,425. Renewed March 26, 1917. Serial No. 157,587.

To all whom it may concern:

Be it known that I, Josnrrr J. OBRIEN, a citizen of the United States, residing at Washington, in the District of Columbia have invented certain new and useful Imrovements in Writing Instruments, of which the following is a specification.

This invention relates to improvements in pen holders and the leading object of the invention is to provide a pen holder adapted for use with removable steel writing points or pens with an ink proof magazine for containing a supply of pen points.

Another object of the invention is to provide a pen point holder with means whereby the pen point may be centered.

A further object of the invention is to provide a pen point holder with a pen holding magazine having an easily manipulated closure adapted to protect pen points arranged in the magazine against ink.

A still further object of the invention is to provide a writing instrument, such as a pen, with a finger seat, whereby the instrument may be easily centered to its correct writing position.

With the above and other objects in view the invention consists in certain combinations, constructions and arrangements of parts, clearly described in the followlng specification and clearly illustrated in the accompanying drawings, in which,

Figure 1 is a longitudinal sectional view through a pen holder and the pen holding magazine thereof, with a portion of the handle or shaft shown in elevation.

Fig. 2 is a transverse sectional view taken on line 22 of Fig. 1.

Fig. 3 is a transverse sectional View taken on line 33 of Fig. 1.

Referring to the accompanying drawings 1 denotes a pen handle or shaft, which, as shown in Fig. 1, is preferably formed hollow to provide for lightness. This handle is circumferentially reduced at one end to receive the end of the pen holding tube 2, and various forms of connection may be employed for holding the handle and the tube together. A special form of connection, however, is shown.

The handle 1 is made of rubber, gutta percha, or other like substance or material, and has embedded therein a helical wire or member 8, which is provided with closely arranged turns 4, disposed on the reduced end of the handle 1. The end turn is of greater diameter than the adjacent turns and forms a spring lock 5, and is adapted to resiliently engage the annular groove 6, formed in the rear end of the tube 2. The rear terminal of the tube 2 abuts against the shoulder 7 formed on the handle or shaft 1, and the groove 6 is located on the tube 2 a sufiicient distance from this rear terminal to engage the lower terminal of the handle or shaft 1. The handle 1 is formed with a series of air openings 8, whereby air may flow through the handle and maintain the same in a cool condition, while permitting the ready evaporation of perspiration.

The tube 2 is formed with a circumferential shoulder 9, located on the outer end thereof, and also with a longitudinal slot 10, whereby pen points may be placed within the magazine or pen chamber 11, of said tube 1, and be removed therefrom.

On the tube 2 a sleeve 12 is rotatably mounted, said sleeve being formed on its rear terminal or end with a circumferential groove 13, which is interlocked with the shoulder formed by the groove 6, and also with a circumferential groove 15, located on the forward end of said sleeve, and adapted to be interlocked with the shoulder 9. The groove 15 is wider than the groove 13 so as to receive the shoulder 16 formed on the rear end of the grip member or inserted tube 17, which is placed within the forward end of the sleeve 12 to hold the pen point in writing position. The body of the grip member or tube 17 is preferably slotted to provide for resiliency, whereby the pen point will be held in secure position, and the rear end thereof is provided with an end wall 18, forming a partition, which, together with the shoulder 16, cooperates with the end wall 19 of the tube 2 and the shoulder 9 of said tube, to effectively seal the pen magazine 11 against ink creeping along the walls of the various tubes. The grip member or tube 17 is spaced slightly from the forward end of the sleeve 12 to provide a space for the pen point, indicated at 20. A plug or filler block or plug 1 is inserted in the forward end of the handle or shaft 1 to close said handle against pen points entering the same. The sleeeve 12 is formed with a longitudinal slot 21, which is adapted to be brought to a position to register with the slot 10, of the tube 1, so that the pens may be removed from the magazine 11, or placed in said magazine. When the sleeve 12 is turned on the tube 1 so that the slot 21 of said sleeve is out of register with the slot 10 of the tube 1, the entrance and exit opening of the magazine will be closed. The sleeve 12 fits snugly on the tube 1 so that no ink can enter the magazine.

The construction described permits a limited supply of pen points to be carried in the pen holder. I/Vhen it is desired to obtain a pen point the sleeve 12 is rotated so that the slot 21 thereof is brought into a registering position with the slot 10 of the tube 2, when a point may be obtained. The edges of the slot 21 form a finger seat for the index finger of the writers hand, or the thumb as the case may be, whereby the pen may be easily centered to the correct writing position.

Having described my invention I cla1m:

1. A. penholder comprising a. handle, a metal tube forming a pen supply magazine secured on said handle, and a tube forming a closure for said magazine and having an end wall and pen holding means located forwardly thereof.
